RAW, yes. The FBT entry specifically states that "It can be affected by powers in the same way that any other creature can be." and later states "Free Actions: Your fey beast companion can take a free action without your taking an action to command it."

As such, by RAW, your beast companion gets the benefit of all of these things.

Of course, it's important to note that the beast companion has pretty marginal defenses, a mediocre attack bonus, and mediocre damage. It's a completely viable target for all enemies (including AoEs) and its primary utility comes from flanking and, especially, the aura bonus.

One of my favorite builds is actually a lazy-lord FBT that uses Commander's Strike and Direct the Strike (with Ninth Legion Student to use your allies for OAs too) with their beast companion nearby in order to be solo viable.
